Patent number: 9800502Abstract: A method includes determining, by a congestion point (CP) unit, traffic flow congestion in an Open Flow environment network. The CP unit comprises an Open Flow switch including a device including logic where an action is associated with each flow entry in the device. A congestion point (CP) unit sends a first congestion notification message (CNM) directly to at least one controller and sends a second CNM directly to at least one reaction point (RP) unit. The CP unit communicates with the at least one controller through a secure channel via Open Flow protocol.Type: GrantFiled: January 13, 2017Date of Patent: October 24, 2017Assignee: International Business Machines CorporationInventors: David Iles, Meenakshi R. Kaushik

Patent number: 9584418Abstract: Embodiments of the invention relate to providing quantized congestion notification (QCN) in networks. One embodiment includes a method that includes determining a traffic flow congestion by a particular congestion point (CP) unit of multiple CP units that communicate with at least one end unit, at least one reaction point (RP) unit and at least one controller in a network. A first congestion notification message (CNM) and a second CNM are generated by the particular CP unit. The particular CP unit sends the first CNM directly to the controller and the second CNM directly to the RP unit. Traffic flow is managed among the multiple CP units by the controller based on the first CNM.Type: GrantFiled: October 10, 2013Date of Patent: February 28, 2017Assignee: International Business Machines CorporationInventors: David Iles, Meenakshi R.

Patent number: 9276843Abstract: In one embodiment, a method for providing virtual link aggregation (vLAG) in a transparent interconnection of lots of links (TRILL)-enabled network, includes creating a virtual routing bridge logically connected to a first physical routing bridge and a second physical routing bridge to form a vLAG group at an edge of the TRILL-enabled network; determining a first distribution tree linking the first physical routing bridge to every other routing bridge in the TRILL-enabled network in a non-repeating fashion, ending with the second physical routing bridge; determining a second distribution tree linking the second physical routing bridge to every other routing bridge in the TRILL-enabled network in a non-repeating fashion, ending with the first physical routing bridge; receiving a multicast packet at the virtual routing bridge from one of the physical routing bridges; and distributing the multicast packet according to either the first or the second distribution tree thereby preventing looping.Type: GrantFiled: October 25, 2013Date of Patent: March 1, 2016Assignee: International Business Machines CorporationInventors: Meenakshi R. Kaushik, Chandramouli Radhakrishnan, Venkatesan Selvaraj, Daljeet Singh

Patent number: 9143444Abstract: In one embodiment, a system includes a TRILL-enabled network that includes a first physical routing bridge (RB) and a second physical RB, logic adapted for creating a virtual RB logically connected to the first and second physical RBs to form a vLAG group at an edge of the network, logic adapted for determining a first distribution tree linking the first physical RB to every other RB in the network in a non-repeating fashion, ending with the second physical RB, and logic adapted for determining a second distribution tree linking the second physical RB to every other RB in the network in a non-repeating fashion, ending with the first physical RB, wherein when a multicast packet is received by the virtual RB from one of the physical RBs, the multicast packet is distributed according to either the first or the second distribution tree thereby preventing looping.Type: GrantFiled: March 12, 2013Date of Patent: September 22, 2015Assignee: International Business Machines CorporationInventors: Meenakshi R.

Patent number: 9036506Abstract: A shortest path first (SPF) computation in a distributed network may be performed efficiently by performing the SPF computation in stages. Rather than perform a new SPF computation every time a change occurs affecting a link state within the distributed network, a routing protocol may identify the change and determine if the impact to the link state necessarily needs the new SPF computation. For example, a predetermined list of events may identify changes that may not necessarily impact the SPF value(s) currently associated with the distributed network. Embodiments disclosed may avoid computation of the new SPF for changes to the link state thus managing network system resources more efficiently.Type: GrantFiled: November 4, 2013Date of Patent: May 19, 2015Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: David M. Bond, Meenakshi R. Kaushik
